I have a 2011 335xi with msport and 16000 miles. At around 100 miles on the odometer, I swapped my msport steering wheel with a m3 wheel. I've had no issues until lately. It sounds like airbag or steering wheel bottles rattle over bumps in the road. I took everything apart today and couldn't find any issues underneath the airbag.

Has anyone had this issue? Maybe it's the steering wheel adjustment lever or a piece of trim in the steering wheel area, but I can not seem to find it.
